Wash the parts with water and dry thoroughly. Remove the pre-cleaner cap to access the
foam pre-cleaner and paper element.
Maintenance
Clean foam pre-cleaner in warm soapy water, rinse and dry thoroughly. Apply oil to the
foam and squeeze out excess oil. The engine will smoke if too much oil is left in the
foam.
Clean the paper element by tapping the element lightly on a hard surface to remove
excess dirt or blow pressurized air (30psi max) through the filter from the air cleaner
cover side. Do not brush the dirt off.
Reassemble the cleaned air cleaner components. Replace elements if damaged or excessively dirty.
Spark Plug
The recommended spark plug is a BPR6ES (NGK) or W20EPR-U (DENSO). To ensure proper
engine operation, the spark plug must be properly gapped and free of deposits. Clean and
replace at scheduled maintenance. Clean engine before removing spark plug. Visually
inspect the spark plug and discard if insulator or tip is damaged. Check that the spark
plug washer is in good condition. If spark plug is to be reused, clean with a wire brush
and set gap .028-.031in(.70-.80mm). Thread the spark plug in by hand to prevent cross
threading. After the spark plug is seated, tighten with a spark plug wrench to compress
the washer.

If installing a new spark plug, tighten ½ turn after the spark plug seats to
compress the washer.

If reinstalling a used spark plug, tighten 1/8 to ¼ turn after the spark plug seats
to compress the washer.
Note:


The spark plug must be securely tightened. An improperly tightened spark plug
can become very hot and may cause engine damage.
Use only the recommended spark plug or equivalent. A spark plug that has an
improper heat range may cause engine damage.

Maintenance
Hardware
Periodically inspect all hardware on the mixer and engine. Loose hardware can contribute to
early component failure and poor performance.
Some hardware is used to retain parts that have to move freely for correct operation
of this unit. These items include the guard lifter and drum guard. The hardware for these
items should be snug enough to prevent excessive play, yet loose enough to allow the parts
to pivot freely.
NOTE:
Wheel Bearing Lubrication
Fill wheel hub with grease to inside diameter of outer races and also fill hub grease cap.
Never use grease heavier than 265 A.S.T.M. penetration (No. 2 grade). Grease bearing cone
by machine or by hand method. Force grease between rollers, cone and cage. (If Ball
Bearing Hub: force grease between balls.) It is not recommended that a pressure grease
fitting be installed on the hub.
Wheel Bearing Adjustment
Tighten the adjusting nut with a 12" wrench, at the same time turn the wheel in both
directions, until there is a slight bind to be sure all bearing surfaces are in contact. Then
back off adjusting nut 1/6 to 1/4 turn or to the nearest locking hole to allow the wheel to
rotate freely within limits of 0.001 inch to 0.010 inch end play. Lock nut at this position.
Drum Seals
Grease zerks daily with lithium based grease.
GEARCASE CLUTCH ADJUSTMENT
If the clutch begins to slip, it must be readjusted to prevent it from becoming overheated
and damaged. For optimum performance, it is necessary to have between 35-55 lbs. pressure
on the clutch lever when engaging the paddles. After the first 25 hours of operation, this
pressure (35-55 lbs.) should be checked to assure proper engagement. It may be necessary
to check periodically after that if the clutch slip. Refer to the GEARCASE ASSEMBLY drawing
for parts identification and proceed as follows:
Caution: Always disconnect spark plug wire(s) or electric cord before attempting to adjust
the clutch.
Counter-Clockwise
1. On gasoline powered models, stop engine and disconnect spark plug wire(s). On
electric powered models, turn off motor and disconnect electric cord.
2. Drain the oil from the gearcase by removing the magnetic drain plug from the clutch
access cover.
3. After draining the oil, remove the (4) 5/16 hex head bolts from the access cover.
Remove the cover and gasket.
4. Make sure the clutch is disengaged by pulling the clutch lever towards the rear of
the mixer.
Buddy by Stone

42
5. Refer to the clutch drawing. Rotate the clutch until the adjustment lock bolt and
adjustment lock are visible.
Maintenance
- on gas powered models it is easier to use the recoil starter to rotate the clutch.
Make sure the spark plug wire(s) are disconnected--do not start the engine.
NOTE
6. Loosen the adjustment lock bolt just enough to release the adjustment lock and
rotate the adjustment lock towards the engine to get it clear.
7. Keep the clutch housing from turning and rotate the adjusting ring one notch at a
time in a counterclockwise direction until a very firm pressure is felt when
engaging the clutch with the lever, as the clutch snaps into engaged position.
8. When the clutch is adjusted satisfactorily, reposition the adjustment lock bolt.
Reinstall the clutch access cover and access cover gasket (make sure the gasket
isn't broken and that it fits properly) with (4) 5/16 hex head bolts and lock
washers. Install the magnetic drain plug into the access cover and tighten the
plug and access cover bolts securely.
9. Remove the oil fill plug from the upper right side of the gearcase and refill the
gearcase with 2 - 1/4 quarts of SAE 90 weight oil. Replace the oil fill plug and
tighten securely.
10.Reconnect spark plug wire(s) or electric cord, start engine / motor and run the
mixer for a couple of minutes. Shut off allow oil level to settle and check for leaks.
Double check oil level, it should be halfway across oil sight glass plug in clutch
access cover.

Maintenance
BELT ADJUSTMENT
Belt tension should be checked weekly. The belts are adjusted by loosening the four bolts
mounting the engine to the engine deck and moving the engine until the desired tension is
obtained. Make sure there is a gap (1/4 inch - 3/8 inch) between the roller on the clutch
lever link and the bottom of the motor mounting plate(See Picture) when the clutch is in the
engaged position. Use a straight edge to maintain sheave alignment while tightening
engine-mounting bolts. If the belts are in need of replacement do not mix old belts with new
belts, replace all belts in the drive system. Check clutch operation for proper engagement
and disengagement after the desired belt tension is obtained to ensure paddle rotation when
clutch is engaged and the paddle rotation stops when clutch is disengaged.
Hand Clutch Adjustment for Belt Drive Units
The hand clutch mechanism for belt drive units uses an over center cam to engage and
disengage the drive train at the engine sheave. Follow the belt adjustment procedure for
proper operation in the engaged position. When the clutch is disengaged, belt tension is
gap between roller and engine deck in engaged position
released and a belt guide applies pressure to the belts to prevent them from coming off of
the drive sheave. The paddles should not rotate in the disengaged position. If the paddles
continue to rotate after the clutch has been disengaged, belt guide or belt tension adjustment may be necessary.
To set the belt guide in the proper location, engage clutch without the motor or engine
running. Set the belt guide so it just misses the top of the belt. The belt guide should not
come into contact with the belts in the engaged position. Belt guide contact with the belt in
the engaged position will cause premature belt wear and possible failure. Check for paddle
rotation after belt guide adjustment is completed. Disengage the clutch and start the motor
or engine. If paddles continue to rotate decrease the amount of belt tension using the belt
adjustment procedure.
